Research on Wind Flow Control by Windbreak Fence for a Large Radio Telescope Site Based on Numerical Simulations

Figure 7

Influence of the top height on reducing wind speed. “NS40-0.5 H” and “NS33-0.5 H” are the simulation results of Section 2.6. “NS” is numerical simulation. “40” and “33” are porosities. “0.5 H” is the height. “1200,” “2000,” and “3000” are the top heights of the computational domain.
